What This Part Does
The 3887328 is a genuine OEM oil pressure sensor that monitors engine oil pressure and sends an electrical signal to the engine-control and monitoring system. That signal drives the oil pressure gauge, triggers fault detection, and activates engine-protection functions if pressure drops outside normal range.
Compatible Applications
Confirmed for selected Volvo Penta gasoline EFI engine families. Always verify against your complete engine model, suffix, and serial number before ordering — Volvo Penta uses multiple sensors in the same engine-control assembly and fitment is serial-specific.

Diagram references: 5.7Gi-300-J, 5.7Gi-300-N, V8-300-A, V8-320-A — 3887328 appears in the electronic engine-control sensor assembly group on these diagrams.
Serial Number Notice
Confirm your complete engine model, suffix, and serial number before ordering. Do not select 3887328 solely because a nearby sensor in the same diagram looks similar — Volvo Penta uses separate pressure, temperature, MAP/MAT, crankshaft, camshaft, and knock sensors within the same control system.
When to Replace
- Erratic or incorrect oil pressure gauge readings
- Oil pressure warning light or fault code
- Pressure reading stuck at an implausible value
- Intermittent electrical signal from the sensor circuit
- Oil seepage at the sensor body or fitting
- Corroded or damaged electrical connector
Always verify actual engine oil pressure mechanically before condemning the sensor on a low-pressure warning.
Installation Notes
- Disconnect electrical power before removal
- Inspect the connector, wiring harness, sensor fitting, and sealing surface during replacement
- Confirm the connector is fully seated after installation
- Check for oil leakage at the sensor fitting
- Verify the oil-pressure reading clears correctly after installation
- Clear applicable engine-control fault codes after completing the repair
- Do not overtighten — follow the torque specification in your engine service manual

Parts Desk Insights
The most common ordering mistake with this sensor is confusing it with the temperature sensor or MAP/MAT sensor located nearby in the same engine-control diagram. The 3887328 is specifically an oil pressure sensor — identifying it by both function and OEM part number prevents substitution errors. If a customer reports an oil pressure warning, always recommend verifying actual oil pressure mechanically before replacing the sensor, as gauge or wiring faults can produce the same symptom.
